With the conjunction of increased life expectancy and the increasing incidence of cancer with aging, older patient represent an increasing proportion of cancer patients. Increasing age is also associated with increased risk of co-morbidities as well as a decline of functional reserve of multiple organ systems, eventually leading in the context of the disease-and/or the treatment-related stress to functional deconditioning or organ failure. Surgery or complex medico-surgical procedures can be considered as one proof-of principle of such risks, since major cancer surgery the older population is at higher risk of morbi-mortality and unplanned hospitalization for geriatric events1. In order to reduce complications after surgery, prehabilitation has often been considered, and 71% of the surgeons would accept a 4 weeks delay before surgery to improve patients' outcomes if shown to be beneficial2. However, the actual level of evidence depends on the interventions: high for pre-operative nutrition3, but low for physical exercise, due to heterogeneous programs with often bad adherence4. In addition, geriatric validated interventions, in order to prevent iatrogenic event, may be added in a multi-interventional model of intervention.
